Tohono O'odham (Papago) and Akimel O'odham (Pima)

O'odham is a Uto-Aztecan language of the American Southwest.
It has two dialects, Tohono O'odham (also known as Papago) and Akimel O'odham (also known as Pima). Speakers of one of these dialects
can fairly easily understand each other, just as speakers of American and Australian English can. Taken together there are more than 10,000
speakers of the O'odham language, most in Arizona.
